2020-2021学年高一下期3月考试 英语试题 本试卷分两部分，共8页。满分150分。考试用时120分钟。考试结束后，将答题卡提交至“家校本”。第二部分阅读理解（共两节，满分40分） 第一节(共10小题;每小题2分，满分30分) 阅读下列短文,从每题所给的四个选项中, 选出最佳选项，并在答题卡上将该项涂黑。 A Dear daughters, Most parents tell their children, “You can be anything you want when you grow up.” I feel the same and I say this often. But I also want you to understand that realizing your dreams comes from hard work, some good luck and good timing. Here are some words of wisdom for you as you make your way in the world, from an entrepreneur (企业家) and from your mama. 1. Be open-minded to changing your path along the way In high school, I wanted to be a politician. I left my hometown and went off to college in Washington,DC. There, I discovered that I loved to support women. It taught me that I’m creative, a strong leader and great at marketing. As a result, I moved on to be the head of a national health-care nonprofit. Becoming a mother while in that job opened my mind to launching a breast pump bag (储奶袋) business. Now I run a highly successful company that I started up on my own. I'm not a politician! 2. Failure is critical to your success Failure can be heartbreaking. But I will tell you that every failure I’ve had along the way has absolutely made me better. Failing the big math exam in high school and going to summer school was embarrassing. I eventually passed, and I’ve never failed an exam again. I learned from that experience to ask for help. Now, I ask for help in business all the time. I’m proud to be a role model to you as a mom and an entrepreneur. I hope I inspire you to believe that you can be anything you want. It will be my pleasure to watch your lives unfold before my eyes. Love, Your mom 21. In the writer’s opinion, what does it take to realize one’s dream? A. Failure, hard work and good timing. B. An open mind, failure and hard work. C. Hard work, good luck and good timing. D. A good dream, an open mind and hard work. 22. What did the writer learn from her failure? A. Failure can make us embarrassed.

2019~2020学年度第一学期期中学情调测 高一语文试题 注意事项： 1.答题前，考生务必将自己的姓名、班级、座位号、准考证号等填写在答题卡上的相应位置上。 2.回答选择题时，选出每小题答案后，用铅笔把答题卡上对应题目的答案标号涂黑。如需改动，用橡皮擦干净后，再选涂其他答案标号。回答非选择题时，将答案写在答题卡上。写在本试卷上无效。 3.考试结束后，将答题卡交回。 一、现代文阅读 （一）论述类文本阅读（本题共3小题） 阅读下面的文字，完成1~3题。 ①美国前国务卿贝尔纳斯退职后写了一本书，题为《老实话》前不久笔者参加一个宴会，大家谈起这本书、这个书名，一个美国客人笑着说“贝尔纳斯最不会说老实话”，大家一笑。贝尔纳斯的这本书是否说的“老实话”暂时不论，他自题为“老实话”，想来是表示他在位时，有许多话不便“老实说”，现在无官一身轻，不妨“老实说”了。 ②古今中外，大家都要求说“老实话”，可见“老实话”是不容易听到和见到的。常听人说“我们要明白事实的真相”，既说“事实”，又说“真相”，叠床架屋，正是强调的表现。说出事实的真相，就是“实话”。买东西叫卖的人说“实价”，问口供叫犯人“从实招来”，都是要求“实话”。 ③人们为什么不能和不肯说实话呢？归根结底，关键是在利害上，自己说出实话，让别人知道自己的虚实，容易制自己，也容易比自己抢先一着。在这个分配不公平的世界，生活好像战争，往往是有你无我，因此各人都得藏着点儿自己，让人莫名其妙。于是乎勾心斗角，捉迷藏，大家在不安中猜疑着。中国有两句古话“知人知面不知心”“逢人只说三分话，未可全抛一片心”。这种处世的格言正是教人别说实话，少说实话，也正是暗示那利害的冲突。 ④老实话自然是有的，人们没有相当限度的互信，社会就不成其为社会了。但是实话总还太少，谎话总还太多，社会的和谐恐怕还远得很罢。不过谎话虽然多，全然出于捏造的却也少，因为不容易使人信。

石家庄实验中学高一英语月考试卷 命题人：高一英语组 阅读理解（每小题2.5分，共25分） A I had a great time this past summer visiting Stone Mountain Park with my twin grandsons. I had the opportunity to spend the day with them seeing the various sights and attractions. One thing that my grandsons had really wanted to do that particular day was to climb to the top of the mountain. Stone Mountain isn't a particularly tall mountain and fortunately has walking trails to the top, but for two 5-year-olds, along with Grandpa, it's a formidable task. Since my grandsons' enthusiasm was much greater than mine, I decided to start the slow walk up the mountain. The beginning part of the trail was slow and gradual. It seemed like we were taking forever to climb just a short distance, but I had to remind myself that it took 3 of their steps to equal1 of mine, so I found myself walking ahead of them, then having to stop and let them catch up, over and over again. I was tired and sweaty, just wanting to get to the top of the mountain so I could rest well before starting my way back. I learned early during our walk that this wasn't going to be the case. We had to stop and look at every large rock with someone’s name carved in it. We looked at unusual plant formations. We examined large trees and we explored small rock overhangs that reminded the kids of caves. My grandsons viewed the walk as an exciting adventure.
